you probably don’t need to disable/enable it , but just purge it afterwards

for that you can use do_action( 'litespeed_purge_all' ); or do_action( 'litespeed_purge_post', 123 ); to purge by post ID where 123 is the post ID

do_action( 'litespeed_disable_all', 'Reason to stop debugging' );

then you can try this

it will be autoamtically turn it on on next request

pseudo code during your import process:

// other ocde 
do_action( 'litespeed_purge_all' ); // purge all before turning off
do_action( 'litespeed_disable_all', 'Reason to stop debugging' );  // turning off on the fly
// your importing process....

then on next request , as long as it doesn’t go into your import code , it will have LSCWP on as it was
